Definitions

  • the present invention relates to a rock working tool meant for mounting on the boring head of a tunnel boring machine.
  • the tool comprises a cutter which with large force is pressed against a rock surface by the tunnel boring machine at the same time as the boring head is rotated.
  • the present invention which is defined in the subsequent claim, aims at achieving a rock working tool which can be loaded substantially more than prior art tools because the tool is cooled during operation.
  • fig 1 shows a rock working tool according to a first embodiment of the invention partly in section.
  • Fig 2 shows an end view of the tool according to fig 1.
  • Fig 3 shows a rock working tool according to a second embodiment of the invention partly in section.
  • the tool shown in figs 1 and 2 comprises a saddle 1 which in a suitable way, e.g. welding along the edge 21, is secured to a not shown boring head of a tunnel boring machine.
  • Two end pieces 2,3 are fastened to the saddle 1 by means of screws which are marked by lines 13,14.
  • the end pieces 2,3 carry a shaft 4 which is provided with a central hole 5.
  • Two rolling bearings 6,7 are mounted on shaft 4. These bearings carry a rotatable ring 8 on which a tool ring 9 is kept in place by a locking ring 10.
  • Two seals in form of steel rings 11,12 are arranged between the rotatable ring 8 and end pieces 2,3 to prevent dirt from entering into the bearings 6,7.
  • Saddle 1 and end pieces 2,3 are provided with channels 15,16,17 to convey cooling liquid to the central hole 5 and to flush cooling liquid on the tool ring 9 and the rotatable ring 8.
  • a pressure liquid source 22 is arranged to feed cooling liquid to channel 15.
  • the embodiment of the invention shown in fig 3, which is the preferred embodiment because of better cooling of the tool ring, comprises a saddle 31 which during operation of the rock working tool is mounted on the boring head of a tunnel boring machine.
  • a shaft 34 is clamped to the saddle by means of two end pieces 32,33.
  • a tool part 8,9 comprising a rotatable ring 8 and a tool ring 9 secured to the rotatable ring by a locking ring 10 is rotatably journalled by means of bearings 6,7 on shaft 34.
  • Seals 36,37 are provided between seal holders 38,39 and the rotatable ring 8.
  • Saddle 31 is provided with a channel 40 extending between a pressure liquid source 22 and shaft 34 for communication with the central hole 35.
  • Saddle 31 is further provided with a channel 41 extending from shaft 34 to a channel 42 to convey liquid to channel 42 for flushing the tool ring 9.
  • Channel 42 is closed at one end by a plug 43.
